To all whom t may concern.'

Be it known that l, CHARLES JoHNsoN, a citizen of the United States, residing at Budalo, in the county of Erie and State of New York, have invented new and useful Improvements in Wheel-Rims, of which the following is a specification.

rl'his invention relates to wheel rims, and more particularly-the rims of automobile wheels having pneumatic tires and including a detachable flanged member for removably retaining the tire on the rim.:

@ne of its objects is the provision of an inexpensive rim of this character in which the detachable flanged member is retained in engagement with the rim-base by the tire, thus dispensing with separate fastening or locking devices for this purpose and materially reducing the cost of the rim.

Additional objects of the invention are to improve the construction ofthe parts with a view of rendering the removable rimmember securely self-locking; and to so construct the rimbase asto facilitate the application and removal of the tire, and so that when the rim is used on a wire wheel, the heads of the spokes will fully clear the removable rim-member as well as the tire,.

to permit easy application and removal of these parts and prevent wear of the tirebase; alsov to produce a rim which by its structure makes it possible -to produce a stronger wheel; also to improve the construction of rims of this hind in other respects hereinafter specied.`

lin the accompanying drawings Figure l is a fragmentary transverse section of a wire wheel embodying the invention. Fig. 2 is a side elevation of the detachable locking ring. Fig. 3 is a transverse section thereof. Fig. t 1s a fragmentary transverse section of a vehicle wheel with a felly, showing the use of the improvement in connection with a wooden wheel. Fig. 5 is a fragmentary face view of the rim shown in Fig. d.

Similar characters of reference indicate corresponding partsfthroughout the several views;

Referring to Figs. L3, i indicates a pneumatic tire of any ordinary construction, that shown in the drawings comprising the custcmary inner tube inclosed by a shoe. The

openings which are preferably formed in cups or indentations 7 stamped in the base of the rim, and in which the heads of the spokes are countersunlr to clear the adjacent portion of the tire shoe. At its outer side the wheel may be provided with the usual double row of outwardly-converging spokes 8, the heads Vof which are seated in similar perforated cups 9, preferably stamped in the bottom of a comparatively wide groove l0 formed by depressing the adjacent marginal portion of the rim-base below vthe level of its main portion. rlhe groove l0 is closed at its outer side by the encircling ring t which is removably seated upon the inner and outer walls of said groove. The outer wall of the groove preferably is undercut or bent toward its opposite wall to form an annular locking iiange il which inclines outwardly, as shown in Fig. i. The ring 5 is provided on its underside near its outer edge, with an outwardlyinclined flange or lip 12 which extends into the groove l0 and bears against lthe inner side of the flange il, thus interlocking therewithand preventing outward displacement of the ring both radially and/laterally of the wheel, when the tire is in'place on the rim, the inward pressure of the tire locking the ring in engagement with the base-flange 11. To increase this locking eect, the inner wall of the groove l0 is inclined outwardly substantially parallel with its outer wall and the ring-flange 12, and the contiguous inner edge of the ring-base is correspondingly beveled or inclined, as shown at it, so that under the pressure exerted against the face of the ring by the tire, the incline of the ringl piacticably aelelocling. Ey tlflis meanse tbe ring is `reliably locked on tbe rino-base Witbout the use of bolts oi otbei1 extraneous fastenings thus not only saving time in ap; plying and removing the tire, but also naatei'ially simplifying its construction and lessening its cost.

As shown in Fig. L tlie locking-Hange il of the rim-base is pleletably depressed belenJv the level of the tace oi tire-seat of tbe base This constinction permits tlie Atite to be easily slipped onto tbe nini-base Without ieeti'aint by the tia-nge ll and likewise facilitates die ifeino'val of tbe tiifec in tlieii pteteifed torni, tbe nig'f'ei tbe flange ll and tbe cointifL l tion of tbe ning are lac-fie- Wardly tance to sure o i retaining; mange 5 ie a piessne of tbe base et tbe A on tlne iiang'e l? by placing tlie,.

isa

Wheels, as -nowmada have 'tbe gage some- Wliat greater than that of Woodenvwheels.

This improved i'im also makes it possible to arrange the inner set ot spokes in a plane perpendicular to the axle or axis of the hub. This produces a Stronger construction and makes it possible to have the spokes O greater tension than in other WineA Wheels, and also gieatly facilitates the ti'ning ot the Wheels. The construction of the removable tiie-ietaining ring of the same outside diameter as tbe integral retaining flange 5 of the i'iin also piodiices a eti'ongei' iiin than one in which said removable ting' is of smaller diameter than the integial flange and holds tlie tiie on tbe Wheel more secuiely.,

Tlie depressed inaiginal portion oi tbe rim-base, moreover, pievents undue spring ing oi tbe tina when tbe spokes are laced oi' tightened, the sinallei' diametei oi that grooved-potion rendering tbe `tino. strengen and stiiilei tlian if it were oit nni'lf diametei1 actoss its Widtli.

By depiessing the beads oi' lacings oi tbe spokes at tbe enter poition ot tlie tina-seat9 the application oli tiie is not only iiacilitated9 but Wea-i" ot its base by tlie spokeiC-lo also the application of the split ring is facilitated by the inclination oit its lip which slips ovei or copeiates with the inclined outer Jace o tbe locking i'lange l1 of tbe Wheel rim.

By extending the basent the locliing icing inwardly and laterally seine distance beyond its locking lip l2, as sbown, the ting-base presents a bearing suiiface oi consideiable atea to the base-*portion of the tite and piacticaily acts as the lowei anni oit a bell-@rank lever which is 'lznlcinnied at 'l5 and Whose uppei aim is torined by' tlie tire-i'etaining flange 5 oil the ring, The icing-base, under the presente oi the in'llated tite, tlius oieis a powerful insistance to a fonce tending to tilt or displace tbe said tire-retaining flange 5 outwardly and latei'ally.

lt will be noted that only tlie enten 'lace oli tbe Ting-lip l2 inteloclis with the locking liange oli tbe Wheel-fini and that tlie innei tace of the lip is spaced at a distance from the opposing innei1 Wall -o'i tbe gioove l0, leaving1 a cleaiance space on the innei' side of tbe lip. nlbis pioyision pievents tlie lip from becoming bound oi' wedged between the Walls of the gioove and facilitates the loosening and detachment olf tbe Ting, paiticulai'ly in case tbe parte should become rusted', l
